Vertebral Hemangioma
A benign vascular lesion within a vertebral body — usually an incidental finding
ICD-10: D18.09 · systemic condition
A vertebral hemangioma is a benign vascular tumor composed of abnormal blood vessel clusters within a vertebral body. It is one of the most common incidental findings on spinal MRI, present in approximately 10–12% of the general population. The vast majority are asymptomatic and require no treatment — they are found when imaging is performed for an unrelated reason and cause significant patient anxiety before reassurance is provided. A small minority (less than 1% of vertebral hemangiomas) become "aggressive" — expanding, weakening the vertebral body, or compressing neural structures — and may require intervention.
10–12%
Vertebral hemangiomas are present in approximately 10–12% of the general population on MRI; they are one of the most common incidental spinal findings.
Baudrez V et al., JBR-BTR (2001)1%
Less than 1% of vertebral hemangiomas become symptomatic or aggressive and require active treatment.
North American Spine SocietySymptoms
- Usually no symptoms — most hemangiomas are incidental findings on MRI
- Localized back pain at the affected vertebral level (in symptomatic cases)
- Radiculopathy (arm or leg pain/tingling) if the lesion expands into the neural foramen
- Myelopathy or cauda equina syndrome in rare cases of severe epidural extension
- Pathological vertebral fracture in rare aggressive hemangiomas that weaken the bone
Causes & Risk Factors
- Congenital vascular malformation within the vertebral body (most hemangiomas are developmental, not acquired)
- Hormonal influence — hemangiomas grow during pregnancy and may become symptomatic
- Unknown trigger for the rare transition from inactive to aggressive hemangioma
Imaging Findings
Imaging studies are commonly used to identify findings associated with this condition. Results vary by individual; a qualified spine specialist interprets findings in the context of a full clinical evaluation.
MRI
- T1 and T2 hyperintense signal within the vertebral body — the combination of fat (T1 bright) and vascular channels (T2 bright) is pathognomonic
- Axial MRI shows a stippled or polka-dot appearance from cross-sectioned thickened vertical trabeculae interspersed with fat
- Aggressive hemangioma: hypointense on T1 (less fat, more cellular), intense enhancement, epidural soft tissue extension threatening the spinal cord
- Cord compression or signal change (T2 hyperintensity) in symptomatic epidural extension
- Note: The T1/T2 bright appearance on MRI is virtually diagnostic — no biopsy required for typical cases
CT Scan
- Coarsened vertical trabecular pattern with intervening low-density fat — corduroy cloth appearance on sagittal CT
- Polka-dot appearance on axial CT from vertically-oriented trabeculae sectioned in cross-section
- Cortical thinning or expansion in aggressive hemangioma — increases risk of pathological fracture
- Epidural component assessment: soft tissue density replacing bone with canal compromise
X-Ray
- Vertical striation pattern within the vertebral body (corduroy cloth appearance) — classic but non-specific finding
- Most hemangiomas are not visible on plain radiographs — CT or MRI required for characterization
- Vertebral body height maintained in benign hemangioma; collapse suggests aggressive or pathological behavior
Who Is Commonly Affected
The following patterns are commonly associated with this condition based on published population studies. Individual presentation varies; these figures are informational only.
Peak Age Range
35–60 years; most commonly found incidentally in adults during imaging for unrelated conditions
Gender Distribution
Female predominance (approximately 2:1); may be influenced by estrogen receptor expression in hemangioma vascular tissue
Estimated Prevalence
Present in approximately 10–12% of the population on spinal imaging; the thoracic spine (especially T4–T8) is the most common location; symptomatic hemangiomas requiring treatment account for less than 1% of all vertebral hemangiomas
Treatment Options
Conservative
- Observation — the standard approach for the vast majority of asymptomatic hemangiomas
- Pain management with NSAIDs and activity modification for mildly symptomatic lesions
- Annual or biennial MRI surveillance for borderline lesions
Surgical
- Vertebroplasty or kyphoplasty — cement injection to stabilize the vertebra and obliterate the hemangioma
- Radiation therapy — used for aggressive hemangiomas not amenable to surgery
- Arterial embolization — reduces blood supply to the lesion before surgical decompression
- Surgical decompression and stabilization — for hemangiomas with significant spinal cord or nerve compression
When to see a spine specialist
If a vertebral hemangioma was found incidentally and you are asymptomatic, routine follow-up with your primary care physician is appropriate. See a spine specialist urgently if you develop progressive back pain at the hemangioma level, arm or leg neurological symptoms, or sudden severe pain that may indicate a pathological fracture. Hemangiomas found during pregnancy or that expand rapidly also warrant specialist evaluation.

Questions to Ask Your Doctor
Bring these questions to your next appointment about vertebral hemangioma.
- 1
Is my vertebral hemangioma asymptomatic and incidental, or are there features suggesting it is "aggressive" (epidural extension, cortical thinning, entire vertebral body involvement)?
- 2
If treatment is needed, what is the most appropriate option — vertebroplasty, embolization, surgery, or radiation — given the location and degree of cord or nerve root involvement?
- 3
Should the hemangioma be monitored with imaging, and if so, how often and by what modality?
- 4
Is there any risk of pathological fracture from this hemangioma, and should I restrict any activities?
- 5
Could my back pain be attributable to the hemangioma, or is it likely from another degenerative source given that most hemangiomas are asymptomatic?
Clinical Evidence
Frequently Asked Questions
Are vertebral hemangiomas cancerous?
No — vertebral hemangiomas are benign (non-cancerous) vascular lesions. They do not metastasize and have no malignant potential. While the word "tumor" is technically correct (it means an abnormal mass), it is not malignant. The vast majority are completely inactive, stable over decades, and require no treatment. The primary risk is not cancer but structural weakening of the vertebral body in a small minority of aggressive cases.
Do vertebral hemangiomas grow?
Most vertebral hemangiomas are stable over a lifetime and do not grow. A small minority — sometimes called "aggressive hemangiomas" — may expand within the vertebral body, extend into the epidural space, or weaken the bone enough to cause a fracture. Risk factors for growth include location in the thoracic spine (especially T3–T9), a vertebral body involvement of more than 60%, and hormonal changes (especially pregnancy). Lesions with these features warrant closer imaging surveillance.
What does a vertebral hemangioma look like on MRI?
A classic vertebral hemangioma appears bright (hyperintense) on both T1 and T2 weighted MRI sequences — a pattern distinctive enough that biopsy is rarely needed to confirm the diagnosis. The "polka-dot" or "corduroy" pattern on CT is also characteristic. Aggressive hemangiomas lose the typical T1 bright signal as fatty marrow is replaced by vascular tissue, and they may show epidural extension on MRI.
